Answer:
Find the ratio in which the line 4x + 3y – 5 = 0 divides the line ... 5), and (2, 4). Also find the point of intersection. pls answer fast. 1 ... Add your answer and earn points.The given points are (−1,1) and (5,7).
Hence equation of the line joining the above points is
7−1
y−1
=
5−(−1)
x−(−1)
6
y−1
=
6
x+1
y−1=x+1
x−y+2=0−−−−−−−−−(1)
Equation of the given line is
x+y−4=0−−−−−−−−−(2)
The point of intersection of the lines (1) and (2) is
x−y=−2
x+y=4
2x=2
x=1,y=3
Let the point (1,3) divide the line segment joining (−1,1) and (5,7) in the ratio 1:k
By applying the section formula,
1=
k+1
k(−1)+1(5)
⇒k+1=−k+5
⇒2k=4
k=2
Hence the line joining the points(−1,1)and (5,7)is divided by line
x+y=4 in the ratio 1:2
